A student and a teacher were arrested for armed robbery. The student and the teacher, represented by separate counsel, were arraigned and released on bond. The teacher reached an agreement with the government to appear as a witness against the student at trial in exchange for a reduced sentence. Upon the request of the district attorney, the teacher asked the student where he got the gun that he used in the robbery. The student said he got the gun from his cousin. This statement was later offered into evidence at the student's trial. The student's attorney objected. How should the judge rule on this objection? (A) Objection overruled, because the student's statement as related by the teacher, although hearsay, was a statement against the student's interest, and thus falls under one of the hearsay exceptions. (B) Objection overruled, because, based on the totality of the circumstances, the student's statement was voluntary. (C) Objection sustained, because the admission of the student's statement to the teacher violated the student's Fifth Amendment right against self-incrimination. (D) Objection sustained, because the admission of the student's statement to the teacher violated the student's Sixth Amendment right to counsel
